title = "Processing resonance self-shielding effect of gadolinia based on imptoved supercell scheme",
abstract = "An improved supercell scheme has been proposed in this paper to efficiently and acc urately process resonance self-shielding effect of gadolinia. Resonance effects are cla ssified into global shadowing effect and local effects involving resonance interferenc e, spatial self-shielding effects. Two categories of effects are decoupled and treated re spectively based on different 1-D cylindrical pins. Hyperfine group method is applied to obtain multi-group cross sections for each 1-D pin. Afterwards, two categories of e ffects are coupled based on a correction formula. Because of the low efficiency for C arlvik method to compute collision probabilities in hyperfine group method, online ta bulation and interpolation method is developed to accelerate gaining collision probab ilities. The proposed scheme is verified against the problems of 3{\texttimes}3 pins with gadoli nia rod, VERA 2O assembly with 12 gadolinia rods and VERA 2P with 24 gadolinia rods. The numerical results suggest promising consistence of multi-group cross secti ons and eigenvalues between the proposed scheme and reference solutions.",
